Sleeps Unexpectedly

[posted this previously, but in general imac group - apologies]
My G5 iMac goes to sleep unexpectedly, usually in the middle of something I don't want to interrupt. It does it
-when I burn audio CDs from iTunes (hour long mp3s)
-when I record audio input from an LP (but not when I record streaming audio from RealPlayer)
-on some heavy web pages (Disney stuff, w/ a lot of flash & audio)...
Pretty frustrating because it kills the tasks. Current theories are
-cpu temperature
-motherboard
-reinstalling select system files
Any ideas?

I've probably already posted this to you somewhere else (the problem with multiple posts-more work and wasted time for us), but just in case;
A number of sleep-related issues can appear after incremental Mac OSX updates, including the inability to properly go to sleep, problems waking from sleep, and having your display go to sleep without your Mac going to sleep. The most common culprit is Bluetooth. Try these tips to fix your sleep problems.
WAKE UP
In System Preferences>Bluetooth, uncheck Allow Bluetooth Devices To Wake This Computer. If you are using a Bluetooth mouse and keyboard, you'll have to wake your Mac by pressing the power button.
FILE CORRUPTION
Your Bluetooth preference file may be corrupt-you'll need to delete it. Turn Bluetooth off, then go to the /Users/user name/Library/Preferences folder. Look for a file called com.apple.Bluetooth.plist and trash it.The OS will create a new preference file when you enable Bluetooth again.
ENERGY SAVER
If you have issues with a Mac or display that goes to sleep at inappropriate times, you may have a problem with Energy Saver. Delete the following .plist files and restart:
-/Library/Preferences/SystemConfiguration/com.apple.PowerManagement.plist
-/Users/username/Library/Preferences/com.apple.systemuiserver.plist--(username is your name or System Administrators name).
-/Library/Preferences/SystemConfiguration/com.apple.AutoWake.plist
A restart is very important after deleting these plists. After a reboot your Mac will then generate new ones.
In some cases, running MacOS X's cron tasks-maintenance that the OS performs automatically if you leave your Mac on 24 hours a day-can resolve many sleep problems. If you don't want to leave your Mac on, you can use MacJanitor, Yasu, or OnyX free at Versiontracker.com.
As Tm311 said, make sure everything in Energy Saver is set to never.
Cheers!

The elgato/eyetv activity seems normal. I didn't find anything leading to a solution at the elgato/eyetv. It was informative; eyetv does interface with the OS to wake the computer to record something and then put it to sleep, but I didn't have anything scheduled to record anything for days. I've updated EyeTV and removed all scheduled recording to see if that helps.

Doh!

Macbook late 2008 goes to sleep unexpectedly

I've started having problems with my MacBook a few months ago. It goes to sleep unexpectedly and sometimes it takes me 30 min to take it out of that state. I've tried utilities like Caffeine to prevent the sleep mode but nothing seems to work. The temperature is fine, the fans work (4,000 RPM) but something is wrong. I read on a few pages that it could be linked to the sensor that actually detects that the lid is closed and automatically puts the MacBook to sleep. I wish I could at least prevent the sleep mode from triggering since I cannot use my mac for work at the moment. I simply cannot rely on it. Any ideas?

Try a SMC reset which governs such things.

Imac stops-sleeps unexpectedly

My G5 iMac goes to sleep unexpectedly, usually in the middle of something I don't want to interrupt. It does it
-when I burn audio CDs from iTunes (hour long mp3s)
-when I record audio input from an LP (but not when I record streaming audio from RealPlayer)
-on some heavy web pages (Disney stuff, w/ a lot of flash & audio).
Each time, it just dies - clicking brings it back as if it was coming out of sleep, but it interrupts whatever was happening previously.
Thanks for help!

Macbook sleeps unexpectedly ?

So for the past two months my Macbook likes to sleep unexpectedly. This happens at all different intervals and may go 2-3 days with no problem and then have 2-3 days with problems. It may go to sleep while taking notes in class and I'll wake it up once and it's fine for the rest of class or I may continually have to wake it up every 20sec-3minutes and finally give up the battle.
This problem ONLY occurs when running on the battery. When the cpu comes back from sleep I notice the battery has an X on it for .2-2seconds and then displays like normal. I have swapped batteries with my gf and the same problem occurs. I have done the SMC reset and it still occurs. I really don't get why it works fine plugged into the the power adapter?
I was wondering if anyone can help me diagnose this? I'm hoping and praying it isn't the logic board because this is an otherwise great cpu that I hate to replace. What are the chances it could just be the battery connector sleep sensor? Errr it really has me frustrated because I take all my class notes on the laptop and I can't depend on it unless I happen to catch a seat next to a power outlet

It sounds like something is wrong with the battery and it's telling the computer it's dead so it goes to sleep. Try another battery and see if the issue persists.

T60p Goes to sleep unexpectedly

My T60p will go to sleep mode unexpectedly. It does this from either battery or when plugged-in. When I try to come out of sleep mode with the Fn-F4 combination of keys it gives me the logon screen takes the password and sometimes goes right back into sleep mode. Other times it works for a while ( 15 - 30 Min) and then just goes to sleep again. It is not consistant. I have all my setting in power management to not go to sleep. Any ideas?
Win 7 64 bit SP1
3GB Mem
Lenovo Toolbox 4.3

i have a similar issue.
I've recently purchased a T500 running Vista 32bit, SP2. After a week or so it has started going into sleep mode or hibernating for no reason. I've checked both the think pad power mode settings and the default Vista options. It occurs very regularly, sometimes in less than 5 minutes since the previous sleep. Then at other times it will not do it for an hour or so. I noticed that after hibernating earlier today it hibernated unexpectedly instead, i.e. it followed my deliberate hibernation with an unwanted one later. Then I put it to sleep deliberately and it returned to unexpected sleeps. I've tried running it on battery and a/c power, run CCleaner regularly, have used Avast, Malware bytes, and Superantispyware recently. I've been lurking around on forums looking for even a coherent explanation of what could possibly cause the problem to no avail.
My unit is second-hand and refurbished, without a brand new battery. Though everything else is in excellent condition. It comes out of sleep fine, never shuts down or hangs.
I'm not sure if it is related, but sometimes when the BIOS details are displayed as I boot up, only sometimes, other info is displayed below the normal 4 lines of white text. it is so quick I can't manage to read it. This too has only begun recently.

IMac goes to sleep unexpectedly, Finder issues with flash drives - related?

My iMac falls asleep for no known reason, often in the middle of active use. (Similar problem recently described in thread with messageID=11829917.)
Sleep onset is frequent but seems to vary based on both currently-running software and attached devices (particularly USB flash drives). It will almost always wake up when I hit the space bar afterward, but might sleep again within a minute or two, then not for an hour or more. The sleep occurs with little notice (brief stall of display, sometimes enough time to click on another app window and bring that forward before the screen goes dark), and 95% of the time the computer wakes up after hitting the spacebar. The other 5 % of the time the display reappears but the entire OS is frozen and usually requires unplugging the power cable. There are other symptoms in the Finder - more below. Once in a while the fan revs up like a WWII fighter plane taking off from a carrier, but this is unusual and all the really irritating stuff also happens without this symptom, which usually stops on its own. Immediately after reawakening error messages are displayed to report that flash drives were improperly disconnected (Tell me about it! This has been the case for several months whether the computer goes to sleep by itself or if I put it there manually.)
The computer seems to go into sleep mode most frequently when not-particularly-demanding graphics (Photoshop Elements and Adobe Reader) and video (QuickTime Pro 7.6.4) apps are running. Turning these off makes nod-offs less frequent but doesn't stop it entirely. When video thumbnails are displayed in Finder windows a lot of time may be required to load the data and this often paralyzes everything else AND this also seems to be a trigger for a nod-off (i.e. QuickTime not necessary to make the computer choke). This is highly variable and some video clips load quickly (< 20 sec), while others take several minutes, and this doesn't necessarily correlate with file size.
Another factor is whether flash drives are connected - these seem to make the nod-offs more frequent AND Finder regularly loses communication to these both while just sitting there and also in the middle of file transfers. A very early 250 MB drive (Lexar - vintage 2004) will always communicate, but different USB2-capable drives all are either unreliable (Lexar 8 GB and KData 4 GB both < 1 yr old) or apparently dead (Lexar 2 GB ~ 2 yr old). The failures may be damaging the drives - they are inconsistent-to-bad at communicating with my MacBook Pro. I know this sounds like the drives are at fault, but there are things which make me suspect the OS (both computers use the same version): 1) different flash drives display the same on-again-off-again behavior AND the 2) the 2 GB drive that hasn't communicated with my Macs in over a month has no trouble talking with my wife's WinXP computer. When communication isn't working with these drives, they do not show up in either Finder or Disk Utility. When the Mac-dead 2 GB Lexar is plugged into either computer and I launch Disk Utility, the initial scan for drives never finishes so I have to force quit. (When they are working, on the iMac the large drives only appear in Finder if I go to User and press Command-uparrow (to go up a directory layer) - in columns display mode nothing appears in the left-hand column.
(The following describes a set of problems I've had a little longer and which may or may not be related):
At times the Finder loses some but not all functions:
1) Sometimes files in the Trash can't be ejected* even when all apps are turned off
2) usually when problem 1) is observed, no keyboard commands work: nothing happens when pressing Command-W, Command-uparrow or Command-N to open a new window. Text typed will not be entered to change filenames (but this can still be done by typing the desired text in TextEdit, copying there and selecting and pasting with mouse commands.)
<* I have downloaded an app for forcing file deletion, but haven't really needed it - the delete option and keyboard commands all return after shutdown and reboot, and there's usually enough annoying stuff going on by this time that that seems the best thing to do.>
Things which I've tried to fix it with so far (not in this order):
- blowing dust out of the back with canned air
- checking temperatures - CPU/GPU showing 72/73, HD bay 51, etc.
- fixing permissions from normal boot
- boot from install disk and running extended hardware test (no problems found during scans repeated several times during the past month)
- fixing permissions and running Disk First Aid from install disk boot
- getting files off the hard drive (was as low as 3 GB free space, currently ~ 35 GB and climbing)
- clearing PRAM
- resetting system manager (name? - hold down power button when reconnecting power cable, etc.)
- Power Saver display and computer auto sleep are shut off (both on "never" - I regularly put it to sleep manually)
- virus scans (Clam XAV)
I realize that this is a kitchen sink collection of symptoms, but these things may be related and if so, OS developers may want to be sure these problems are avoided in current versions. (Yes I will upgrade my OS soon...)

Thanks for checking in, Miriam - sorry to get testy about it.
The iMac's RAM is maxed out (2.5 GB)
Yes, the system log does report overtemp message to Power management prior to shutdown (today's log at end of post)
Where do I find normal temperatures for the system? What are the important parameters to watch and what sort of fixes are possible?
iStat currently shows:
HD 54° CPU 67° GPU 72° Incoming air 38° (???)
HD bay 54° GPU ambient 71° opt drive 49°
==========================================
Console.log was largely full of stuff about a bad flash drive I stuck in as a Hail Mary and failure of communication with a scanner (old HP, driver package installs a program which starts at launch which doesn't show up under Startup Items. Apparently the permission got mislaid, so I fixed permissions and this seems OK now. (Only included that because some of it shows up in System.log and it's not worth focusing on.)
[That all said, there is a software/OS component to the problem and it is graphics-related. The other night I was looking at some flash videos in a series and one in particular repeatedly caused shutdown, while others played normally: domain = jebhost.com /youtube/list.php?q=Henry+8.o&Submit=GO "The Tricycle Thief" only played through once out of about six tries.]

MBP sleeps unexpectedly, black screen shows " z z Z" I've NEVER seen before

I found plenty of posts on Macs NOT sleeping. I have the opposite.
About an hour ago, abruptly my screen went black except for three "Z"s in the middle, stacked lopsidedly. Seems pretty evident that it's put my MBP to sleep. I click the spacebar and return; it takes maybe 10-12 seconds to come back up (usually it's instantly when I hit it that quickly).
I checked my Sleep and Energy Saver settings. As usual: computer NEVER sleep, display sleep at 5 minutes. As it happened several times, I wondered if it were getting that 5-minute interval somehow. I upped it to 15 minutes, and it did "z z z" again, but at something like 17-18 minutes (hadn't noted the seconds), so that seems to rule out it getting some instructions from that preference.
The only plist I recognized as possibly involved: com.apple.preference.desktopscreeneffect.plist
Made no difference. It happened again just a few minutes after I moved that to the desktop. Does anyone have any ideas about some other plist to which this may relate?
I can't find ANYTHING online reporting this. And as a Machead since 1986, I don't recall ever seeing this kind of sudden sleep.
Recent installs: a week or two ago I did install a "Fireflies" screen saver, which is basically a more lively variation on Apple's "Flurry." I used it for a few days, no problem, then went back to something else. I did start it up again last night, but I had no problem then.
Still troubleshooting, I've changed my Energy Saver to "Never" for both computer and screen. As I'm typing this, the last "Z Z Z" happened over a half-hour ago.
And WHOA — for just a moment, right then, I saw a probably briefest-possible black screen — but it didn't continue to the "z z z."
Has anyone ever seen this happen? Any other plists or apps to suggest?
Thanks,
Chuck B

Heh, you read my mind on this. When I first started using Keynote I did deliberately pair it for only my MacBook, to PREVENT problems. Now I may undo that, because I can think of a few people with whom I might play around a little — who wouldn't mind the joke.
Of course, if, unlike me, they already know the remote does that, they'll probably just turn around and say "CUT IT OUT ALREADY."
Obviously you're way ahead of me on Mac stuff, so you probably already know ctrl-opt-cmd-8 as a toggle for reversing the screen colors, another funky little trick.
Danke!

Mac pro sleeps unexpectedly

I've a Mac Pro (mid 2010) 8core 2.4 runniing Maverick/ 32gig ram, In the last couple days she'll go into sleep mode for no reason and i've all my energy settings turned off, it doesn't get out of sleep mode when i tap the keyboard, trackpad/mouse or power button? I have to litterally turn the unit off and reboot, only for the same thing to happen again?
Any help would be appreciated.

I cleaned out my mac with compressed air, it was dusty, but the display flickering happened again.
So I followed your advice and installed:
Temperature Monitor
http://www.bresink.de/osx/TemperatureMonitor.html
Which showed that my memory module 1B and 2B were 70 - 75'C(160 -167'F). There was no reading for the graphic card so I couldn't tell if that was over heating.
Then I installed:
smc fan controller
http://www.macupdate.com/app/mac/23049/smcfancontrol
and increased the memory_cpu fan speed which lowered the temperature of the ram to 60'C (143'F).
I even changed this ram's placement and put it in different slots.This ram was the same temperature in the new placements.
Also this is the kingston 2gb ram without heatsinks. Ive used it for 1.5 yrs, and this is the first time its giving me these problems.
Do you know how I can check if the graphic card is over heating? or is the problem just with the ram?
Thank you for all your help!

Drobo shuts down unexpectedly if connected to Airport Extreme

the first 2 weeks worked flawlessly. now every other day for no reason the drobo must be loosing some level of contact with the AE because it goes to sleep unexpectedly. and s soon as I reboot the AE it comes back to life. the Drobo does not do this if connected directly to the Mac. any ideas what is wrong

I actually have the same problem. I've had my drobo for a while now and I have been using it with my mac via firewire. I recently switched to use it with usb on my AE because I wanted to share it throughout my network and I started doing this. Not sure what the problem is but it needs to be fixed.

My Macbook pro, (late 2010) sometimes will sleep and won't wake up. then the sleep light flashes.What's the problem?

My Macbook pro, (late 2010) sometimes will sleep and won't wake up. then the sleep light flashes.What's the problem

Hi I've been following this thread (along with a different one on the same topic). I've been having the same problem with my ibook. I can add that I have no problem with startup. It's just that the screen "goes to sleep" unexpectedly and may operate normally for a few minutes or a few hours at most. Opening and closing the lid or restarting seems to cause it to awaken but then usually for just a few seconds or minutes. If it is connected to another video display that display continues functioning fine even though the computer screen is blank. In addition the desktop is there and visible faintly or if totally blank can be backlit through the apple logo and can be read. I've had my logic board replaced twice under the extended warranty and assumed it was that but now I'm thinking of the reed switch. Apple refuses to consider any further work under warranty as the last repair was in Jan, 06 and they claim only a 90 parts warranty and the machine is from 03. Any thoughts before I cut the wires? I have reset the pmu, run cocktail and disk utility. Other than the sleep issue the machine works fine. thanks Ronda or anyone else who has any ideas... Dave

It sleeps without my permission

This afternoon, my MacBook went to sleep. It should't have, because it had 1 hr + of battery power remaining, and I was actively using it. When I woke it up, it just went to sleep again...and again. I was able to keep it awake just long enough to shut down the computer and start it again. Then the same problem occurred, and I even had to wake up the computer while it was shutting down (it did then shut down).
When I got home and plugged it in, it went to sleep unexpectedly again, but when I woke it up, it stayed awake.
Is this an issue that I can resolve on my own, or should I just resort to AppleCare? I appreciate any feedback on this issue.
MacBook Mac OS X (10.4.8)

It should. You can also double check the charge in your battery by manually pressing the button on the bottom of the battery - this will give you an LED read out of its charge. If it doesn't come around it may be a faulty battery.
Double check your Sleep settings as well (both Battery & Power Adapter).

MBP mid-2009 going to sleep by it self

Hi,
since I updated to Yosemite my MBP has been going to sleep by it self, I will say every 15min or so. Before it goes to sleep it ask me if I want to close all my programs and it gives me 59sec. to make a decision.
I have set my computer to never go to sleep, either charging or not, and stills doing this. I find it really annoying because if i'm not in my computer it will close all my programs and I will have to open everything again.
Any help on this??
thx

Greetings jchapui,
If you are having an issue with your MacBook Pro going to sleep unexpectedly, I would suggest resetting the computer's System Management Controller. This article explains how -
Intel-based Macs: Resetting the System Management Controller (SMC) - Apple Support
Sepcifically -
Resetting the SMC on portables with a battery you should not remove on your own
Note: Portable computers that have a battery you should not remove on your own include MacBook Pro (Early 2009) and later, all models of MacBook Air, and MacBook (Late 2009).
Shut down the computer.
Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
Release all the keys and the power button at the same time.
Press the power button to turn on the computer.
Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.
Thanks for using Apple Support Communities.
Be well,
Brett L

HT3964 My computer freezes after running for about 15 min even after setting the energy saving to 3 hours

My Mac computer freezes after running for 15 min even after seeting the energy saving to 3 hours. Any ideas how to stop the freezing/

Hi Teodorafrombc,
Thanks for visiting Apple Support Communities.
If your computer is becoming unresponsive, you may want to see if specific applications are causing this behavior. Try using the Force Quit menu to check for unresponsive applications:
Using the Force Quit feature of OS X makes an application close, even when it is not responsive.
Important: Normally you should not need to force quit an app to close it. When an app is forced to quit, any unsaved changes to open documents are not saved, so try these methods to normally close the app first:
Choose Quit from the app menu. For example, in Safari, choose Safari > Quit Safari.
Choose Quit by right-clicking or control-clicking on an app's icon in the Dock
You can find the article with these steps here:
OS X: How to quit an unresponsive application using Force Quit
http://support.apple.com/kb/ht3411
If your display is going blank or seems to be going to sleep unexpectedly, try these steps first:
Reset the system
You can reset the Mac's parameter RAM and SMC.
You can find the article with these steps and more information here:
Apple computers: Troubleshooting issues with video on internal or external displays

If these steps don't resolve the issue, feel free to reply with more information about the symptoms you are experiencing.

My screen gets tunnel vision

My MacBook Air froze up a few times. The screen went dark with a faint image in the center. It was as if it was in sleep mode, but I could not wake it up. I played with the brighten buttons (f1 and f2) and it eventually woke up. The screen sometimes changed when the computer woke up. The curser was working even though I could not see what it was on, so it would sometimes change the screen by clicking something I couldn't see. Is this a glitch? Did I inadvertently change a setting? Has this happened to anyone else?

Hi slowplodding,
Thanks for visiting Apple Support Communities.
If your display goes dark or your computer seems to sleep unexpectedly, I recommend first trying the steps in the "Additional troubleshooting" section of this article:
OS X: When your Mac doesn't sleep or wake
http://support.apple.com/kb/TS5357
Reset SMC
The System Management Controller (SMC) is involved in managing power on your computer. Reset the SMC on your Mac if you are having difficulty sleeping or waking your computer.
Reset NVRAM/PRAM
Nonvolatile RAM (NVRAM)/Parameter RAM (PRAM) stores some power-related settings.Try resetting NVRAM/PRAM if you are having difficulty sleeping or waking your computer.
Test with external devices disconnected
Some external devices can prevent your computer from sleeping. Try disconnecting items other than your Apple keyboard or mouse from the built-in USB, Thunderbolt and Firewire ports on your Mac. If this resolves the issue, try reconnecting your external devices one at a time until you find the device preventing sleep or wake. Check the documentation that came with the device, or contact the device manufacturer for more information.
Try Safe Mode
Check to see if the issue still occurs when the computer is started in Safe Mode. If this resolves the issue, it could be related to a third party software item such as:
a login item
a startup item
a third party kernel extension
Try another user account
Try creating another user account, or log in as guest. See if your computer sleeps and wakes properly from the additional user account. If it does, your issue may be related to one of the following:
a login item
an app open in the original user account
You can disable login items from the Accounts pane of System Preferences. Try opening only one app at a time in the original user account to determine which app is preventing sleep. If you isolate the issue to a particular app or login item, check its documentation, or contact the developer of that software for more information.
Cheers,
Jeremy
